Application Range; Use Notice Points - toscano TDS600 Serie Manual De Usuario

1.2. Application range
This kind of inverter apply to 3 phase ac asynchronous motor only for general
industry.
It should handle cautiously and consult with manufacturer when inverter apply
to high reliability required equipment which relevant to life, properties and
safety device.
This kind of inverter is the general motor control device in industry. When
inverter apply to dangerous equipment, safeguard should be considerable in
case of inverter failure.
1.3. Use notice points
01. TDS600 series inverter belong to voltage type inverter, and it is normal
with up temperature, noise and vibration of motor increasing over power
frequency run slightly.
02. It is required to match inverter with variable frequency motor running
at low speed with constant torque for long time. When match inverter with
general asynchronous motor running at low speed, it should take measures
to make motor heat dissipation or monitoring motor temperature in avoid of
motor flash.
03. It is necessary to take measures in advance for the damage caused for
the bad lubrication of the reduction box and wheel gear mechanical devices
running at low speed for long time.
04. It is necessary to assure at first that the use speed range of motor
bearings and mechanical devices, also the increasing of motor vibration and
noise should be considered, when motor run over rated frequency.
05. It is necessary to select the suitable brake assembly for hoisting device
and big inertia load to make sure the normal work when inverter stripping
from power grid for the overcurrent or overvoltage failure.
06. Inverter start and stop control through terminal or other normal command
channel, otherwise it may cause inverter damage via connecting inverter
input terminal to big current switch just like contactor direct to start and stop
inverter frequently.
07. It is necessary to make sure inverter cut off from operation without
output, when inverter and motor connect through switch components just
like contactor etc. Otherwise it will cause inverter damage.
08. When inverter output frequency within some range, it may meet
mechanical resonance point of load device, through setting jump frequency
to avoid it.
